EXTENSION-HANDLE FOR EXERCiSlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 232,218, datedSeptember 14, 1880.

Application filed September 30, 1879.

To all whom it may concern.-

Be it known that I, EDWARD A. TUTTLE, of New York city, in the countyand State of New York,-hnve invented a. new and useful Improvement inExtension-Handles for Lifting' and other Machines, (Case 0,) of whichthe following is a. specification.

This invention consists in on improvement in the lifting-handles ofhealth-lifts and other in nchin es requiring to belen gthened andshortened at will to suit the requirements of different persons, wherebythey are made much simpler both in construction and operation, and alsomore certain and reliable than as heretofore made.

Figure lis a side elevation of my improved handle. Fig. 2 is a sectionalelevation of it, and Fig. 3 is a perspective view of one of the parts.

The bar of the handle is constructed in two parts, A and B, one ofwhich, preferably the lower one, A, consists of a kind of skeleton tubewith, an ellipticnl sbaped bore, formed of upright bars 0 and cross-bers I), while the other is a rod, E, with notched win gs or flanges F.In this case two of the cross-bars D are made to encircle the rod E onone side and one on the other; but there may be as nanny more of thesebars he preferred, or instead of separate bars there may be continuousside plates to the upright bars 0 5 but in that case the insides willhave recesses corresponding to the spaces between the cross-bars. Thisskeletch-tube and the winged or flanged rod ll are so shaped andproportioned relatively to each other that the letter will slide up anddown freely in the former. When the flanges are set in the plane of thegreatest diameter oi the space or bore included within the bars it istoo wide and cannot be turned into or set in the other or shortdiameter, except when the bar E is adjusted and the notchesin the wingsor flanges are set to coincide with the crossbars D for that purpose,and thereby cngag ing with said bars to make the connection for lifting.Any number of these notches may he had in the bar E, according to thelength of the extension required.

Stud-pins fitted in the sides of the her E will serve thesomepnrpose asthe notched flanges;

but I prefer the letter forbeing cheaper to make.

It will be noted that the ansngernent of the notches and the cross ba rsis such that the connections of the one with the other for liftlog areestablished when the handles B are in the natural positions for thehands of the oporator in the actof lifting, and that said. handies mustbe turned at right angles to such positions for shifting; hence,although the disconnection is, so easy to ma kesimply by turnin g thehandles-yet thereis little or no liability of it happening whilelifting, es the operetor has entire control of the handles at such time.

The most simple and preferable method of constructing this improvedextensioirhandle is to make it in malleable cast-iron or other ductilemet-n1 but it may be forged or otherwise mnde, if desired.

It will be noted thstthe cross-bars D of the opposite sides of thelengthwise bars 6 are orrnnged alternately to each other-that is to say,the bar of one side is midway between those of the other side, whicharrangement hss three important advantages as compared with that ofplacing them opposite to each 0t118iVlZ., it does not require so manycrossbars, it enables the bar A to be molded without a. core, and itpermits the some alternation of the notches oi the rod E, which makes itstronger than it would heif its notches were opposite, and enables a.finer adj ustment of the handle with the seine number ofcrossbers andnotches.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-- 1. The combination, in an extension-handle forlifting and other machines, of a, skeleton tubular bar, A, and a rod, E,with notched ribs or flanges, substantially as described.

2. The cross-bars 1), arranged nlternatel along the opposite sides ofbars 0, in combo nation with the similarl alternating notches of the rodE, substsntia iy as described.

EDWARD A. TUTTLE.
